While a differential may also provide gear reduction, its primary purpose is to permit the wheels at either end of an axle to rotate at different speeds ( essential to avoid wheel slippage on turns ) as it changes the direction of rotation.

The GO-300's tainted reputation was largely undeserved, since its problems were the result of pilots who were unfamiliar with gear reduction engines simply not operating the engine as specified in the C-175 Pilot's Operating Handbook.

The VW air-cooled engine does not require an expensive and often complex gear reduction unit to utilize a propeller at efficient cruise RPM . With its relative low cost and parts availability, many experimental aircraft are designed around the VW engines.

The aircraft were initially powered by 1600 cc Volkswagen air cooled engines of using Lloyd Patner's gear reduction units driving 3-blade Fahlin props, but later Continental O-200 and Lycoming O-235s were used along with the Rotec R2800 radial engine.

In 1962, Chrysler introduced a starter incorporating a geartrain between the motor and the drive shaft . The motor shaft included integrally cut gear teeth forming a pinion that meshes with a larger adjacent driven gear to provide a gear reduction ratio of 3.75 : 1.
36.
The troublesome geared "-8b " model was prone to have serious gear reduction system problems, sometimes with the propeller ( and even the entire gearbox on a very few occasions ) separating from the engine and airframe in flight, a problem shared with the similarly-powered Sopwith Dolphin.

This front-drive, five-door SUV with a choice of two-or four-wheel-drive will offer a unique item : a continuously variable transmission ( CVT ) that uses a pair of variable-diameter pulleys and a steel belt to match engine output to vehicle speed and provide gear reduction without step shifts.
38.
Freedom Drive I and Freedom Drive II, Freedom Drive I is a full-time four-wheel drive system with locking capabilities; Freedom Drive II is based on Freedom Drive I but by using the vehicle's CVT transmission it is capable of a 19 : 1 gear reduction simulating a low-range usually found in vehicles with dedicated transfer cases.

The cost to build a " Handy Henry " made from an old Model T car or truck was about $ 20, according to the 1936 edition of the Handy Man's Home Manual, and this provided a serviceable vehicle with rubber tires, a big truck rear end and two transmissions to make up for the gear reduction with which the kits came.
40.
For every 3.23 revolutions of the smallest gear, the largest gear turns one revolution, or for every one revolution of the smallest gear, the largest gear turns 0.31 ( 1 / 3.23 ) revolution, a total reduction of about 1 : 3.23 ( Gear Reduction Ratio ( GRR ) = 1 / Gear Ratio ( GR ) ).
